    Hydrodynamic stability of He II periodic boundary layer flows

  • Original language description

    He II periodic boundary layer experiments on the damping of torsional oscillations of a sphere have been re-analyzed based on recent classical stability theory. We show that macroscopic He II periodic boundary layer flows exhibit instabilities that are described by classical stability criteria if the kinematic viscosity is regarded as the dynamic viscosity is regarded as the dynamic viscosity over the total fluid density.

    Hydrodynamická stabilita periodických proudění s hraniční vrstvou v He II

  • Czech description

    Periodická proudění s hraniční vrstvou v He II experimentálně studovaná jako tlumení torzních oscilací koule byla analyzována na základě nedávných poznatků klasické teorie stability. Prokazujeme, že tato proudění He II vykazují nestability, které lze popsat klasicky, je-li kinematická viskozita uvažována jako podíl dynamické viskozity ku celkové hustotě kapaliny.
